Mini-van
Premiere: April 6, 2013 @ 8:00 AM
Network: TV Tokyo
Studio: DLE
Comment: Listed by Countdown and FansubDB. The series was also earlier confirmed by ANN, but with no mention of the premiere season or date.

Countdown is missing Yondemasu yo, Azazel-san. 2 so I know it's not on that chart.

Based on what's confirmed for Spring, very interested in:
The remaining episodes of Girls und Panzer
Dansai Bunri no Crime Edge
Date A Live
Gargantia on the Verdurous Planet (Gen Urobuchi tends to interest me.)
Hayate no Gotoku(2013)
Oreimo 2(if Crunchyroll simulcasts this, they need to have the OVAs so people aren't confused by suddenly seeing Kuroneko at Kyousuke's school. Kuroneko is the best part of that show.)
Photo Kano
RDG Red Data Girl (I am always interested in PA Works)
The Hentai Prince and the Stony Cat.

Have a feeling that Funimation will be busy and that Viz will snag at least a few shows(They getting Arata Kangatari wouldn't surprise me)
